who we are

Colégio de S. Tomás is a Catholic school founded in 2003 by APECEF - Associação para a Educação, Cultura e Formação.

Our Debating and Great Figures contests, the Science Fair and Open Day are some of the highlights and features of life at Colégio de S. Tomás, which aims at offering wholesome experiences in which each student can discover and enhance the true self.

Debating and Great Figures Contests

In the Debating Contest and the Great Figures Contest, Colégio de S. Tomás gives students the opportunity to develop their communicating, debating and critical analytical skills. It is part of our mission to build a school that is a place of culture.

Science Fair

Students are invited to take part in the Science Fair with questions of their own viewed through the scientific method, as part of the experimental learning that the school encourages.

Open Day

We hold an Open Day to provide an opportunity to communicate what we live and learn in day to day life at Colégio de S. Tomás. It is held every year on the closest Saturday to St. Tomas’ day, 28 January, and is an opportunity for our students to acknowledge and present their work in a broader perspective.

Where are they now?

The requirements and extensive curriculum of CST meant I was easily able to adapt to the different realities that I encountered throughout my international experiences, as a student and as a person.

Colégio de S. Tomás gave me: development of a working method, encouragement and motivation, adaptability and curiosity. It gave me friendships that have lasted to this day, and which will certainly last much longer.
